The feeding mechanism of gars (Ginglymodi : Lepisosteidae) is characterized by cranial elevation and lower jaw rotation but minimal cranial kinesis. Gar jaws have numerous, sharply pointed, elongate teeth for capture of evasive prey. Their mandibles range from relatively short to extremely long depending on the species.

Riboflavin in the eyes of gars (Lepisosteidae)
Canadian Journal of Zoology, 1972Eyes of gars (Lepisosteidae) have a yellow tapetum lucidum containing an as yet uncharacterized yellow pigment. They also contain fairly high levels of riboflavin, about 14 mg/100 g wet weight, which lies in tissues external to the retina and tapetum and which is, therefore, not a tapetal pigment.

Late Cretaceous (Santonian) Atractosteus (Actinopterygii, Lepisosteidae) remains from Hungary (Iharkút, Bakony Mountains) [PDF]
Cretaceous Research, 2016 Lepisosteid fishes are well known from the Upper Cretaceous of Europe, but only by fragmentary remains from some Cenomanian and Campanian–Maastrichtian deposits. Here we report various cranial and postcranial remains of gars, discovered in the Upper Cretaceous (Santonian) Csehbanya Formation of Iharkut (Bakony Mountains, Hungary).

The tapetum lucidum of gars (Lepisosteidae) and its role as a reflector
Canadian Journal of Zoology, 1974Eyes of four species of gars were studied, namely, alligator (Lepisosteus spatula Lacépède), spotted (L. oculatus (Winchell)), shortnose (L. platostomus Rafinesque), and longnqse (L. osseus (L.)). The retina is duplex, a yellow tapetum lucidum is present, rods and retinal pigment move, and the tapetum is uncovered in dim light. The visual pigment is a

Studies on the eyes of gars (Lepisosteidae) with special reference to the tapetum lucidum
Canadian Journal of Zoology, 1973Eyes of gars (Lepisosteus) possess a yellow tapetum lucidum which is located in processes of the pigment epithelium. A yellow reflecting pigment is involved, enclosed in tapetal spheres each about 240 nm in diameter. Retinomotor movements take place: in darkness (or dim light) the black retinal pigment retracts, exposing the tapetum, and the rods ...
